Instagram has so far been limiting the resolution of the photos uploaded to the social network. Despite having mobiles with high-resolution screens, the social network owned by Facebook has limited the size to 640x640
Apparently, Instagram is testing a new resolution that reaches 1080x1080, the double of the current resolution With this, it would show up much better on mobile phones and it is practically a perfect size for most devices. On the computer it would be somewhat limited.
Even so, Instagram will continue to compress the photos and crop them to leave them in square photos This means that we will always lose part of the photograph, which we will have to select previously. Then Instagram will take care of compressing the image and leaving it at a size of 1080x1080.
Remember that 1080x1080 is similar to Full HD quality, although it is not exactly this, since the format is square. Of course, it is high resolution and suitable for most devices. And it is that 640x640 is quite little in these times, where we already talked about QHD screens on mobile even. In addition, Instagram is also preparing to not only be a mobile app but also have a decent web version.
At the moment Instagram has not confirmed these changes but they are already evident in a large part of the photos that we upload at the moment of the apps mobile. It is expected that it will finally become official and the mobile apps for iOS and Android will use the size 1080x1080 as standard
